False Angelwing

De Amerikaanse boormossel Petricolaria pholadiformis kwam oorspronkelijk enkel langs de oostkust van Noord-Amerika voor, maar werd omstreeks 1890 naar Europa gebracht (Engeland) samen met het transport van Amerikaanse kweekoesters Crassostrea virginica. De planktonische larven van de boormossel konden vervolgens de rest van Europa bereiken door mee te liften in zeestromingen. De soort werd voor het eerst in Belgische wateren waargenomen in Nieuwpoort in 1899. Nu leeft de soort vooral ter hoogte van onze oost- en middenkust. Deze tweekleppige boort gangen in turf- en veenblokken, hout, harde klei en kalksteen. In aanspoelende veenblokken zijn vaak levende individuen terug te vinden. Lege schelpen spoelen vaak aan op onze stranden.

The natural distribution area of the false angelwing Petricolaria pholadiformis was limited to the east coast of North America, but was brought to Europe (England) around 1890 together with the transport of the eastern oyster Crassostrea virginica. The planktonic larvae of the false angelwing could subsequently reach the rest of Europe by hitch hiking on the sea currents. The species was first observed in Belgian waters at Nieuwpoort in 1899. In Today, the false angelwing can mainly be found along the east part of Belgian's coast. This bivalve drills passageways in peat blocks, wood, hard clay and limestone. Living individuals are often found in washed ashore peat blocks. Empty shells are frequently found on Belgian beaches.
